‘I have to admit I was wondering “How am I going to peel this?”

She added: ‘The fact that somebody has actually picked it up to put a sticker on it not once, but twice on the shop floor so to speak, you would think somebody would have noticed it – because it is actually quite heavy.’

Tesco said it is looking into what happened.

A spokesperson for the supermarket said ‘We sell millions of bags of potatoes every week and our growers work hard to inspect them carefully, however this sort thing can happen on very rare occasions.

‘We have asked our customer to return the potatoes to their local store so we can investigate the complaint.’
